Part Number : STR W5753A
Function : Flyback Switching Regulator
Package : TO-220 6Pin Type
Manufacturers : Allegro, Sanken
Description
The STR-W6753 is a quasi-resonant regulator specifically designed to
satisfy the requirements for increased integration and reliability in
switch-mode power supplies. It incorporates a primary control and drive
circuit with an avalanche-rated power MOSFET. The regulator exhibits
only low-level high-frequency EMI noise because of soft switching of
the MOSFET close to ground (bottom point). A bottom-skip function
minimizes an increase of operational frequency during light loads to
improve system efficiency over the entire load range.
